Although allergy, asthma and other atopic diseases are my specialty, the spectrum is different in the pediatric setting. Sounds like you experienced a fairly substantive game of urticaria and angio edema. In children, both symptoms are very common and rather few are accompanied by more severe, life threatening symptoms like asthmatic reactions and anaphylaxia.

Most of these reactions are of unknown origin but many of them are caused by viral infections and as such not a 'true' allergic reaction. Those with known multiple allergies, not least from food, will of course suffer from specific allergic reactions and as such running a higher risk of more severe reactions. However, even in these cases it is often impossible to pin point the exact culprit. Many times our immune system reacts unpredictably. One single allergen might not evoke a reaction, but in combination with others the immunological reaction may (or may not) run amok.

In your case it might have been one or probably several different air borne allergens cooperating - together with you straining the system.

A certain fact is that no matter what level of original allergic reaction - exercise will very much raise the risk of more severe symptoms.

Impossible to give any specific advice long distance as usual, but as previously stated, it is probably not a bad idea to have both cortisone and an adrenaline pen like Epi-pen or Ana-pen handy. First of all I would however see a doctor with this specialty.

Oh, and I would definitely take an anti histamine daily all year. The local topical medications for nose and eyes are fine for the local symptoms, but they do not block the systemic allergic reaction which is paramount in lowering the risk for systemic more severe reactions. They are also harmless in modern iterations.

Excuse my bad spelling. Spell check did not work.
